What are the key features of LM34925SDX/NOPB?
- Wide input voltage range of 9 V to 100 V supporting high-voltage industrial and 48 V telecom bus applications
- Constant on-time voltage-mode control enabling fast transient response with minimal external compensation network
- Pb-free 8-pin SON package (JESD-30 S-PDSO-N8) with compact footprint for dense power stage layouts
What is LM34925SDX/NOPB used for?
The LM34925SDX/NOPB is designed for high-voltage step-down (buck) converter stages in industrial automation, factory control systems, and 48 V telecom infrastructure equipment. Its wide 9 V to 100 V input range covers both standard 48 V bus and transient-heavy environments such as automotive 24 V truck systems and solar charge controllers. The constant on-time control scheme makes it suitable for point-of-load converters requiring fast load transient rejection without complex compensation tuning.

Frequently Asked Questions
What input voltage range can LM34925SDX/NOPB regulate from, and what is the nominal bus voltage it targets?
LM34925SDX/NOPB operates across an input range of 9 V to 100 V, with a nominal 48 V operating point typical of telecom and industrial bus standards. This wide range means a single controller can service systems ranging from 24 V truck supplies up to 100 V photovoltaic bus rails without redesign.
How does the constant on-time control mode of LM34925SDX/NOPB benefit high-voltage power supply designs?
Constant on-time voltage-mode control in LM34925SDX/NOPB enables inherently fast transient response with a near-instant duty cycle adjustment each switching cycle. Compared to fixed-frequency PWM, this allows the converter to recover from a 10 A load step in fewer than 5 µs while requiring fewer external compensation components, simplifying the feedback network design considerably.
For a 48 V industrial power rail design, what package and footprint does LM34925SDX/NOPB use on the PCB?
LM34925SDX/NOPB comes in an 8-pin SON (small outline no-lead) package with a compact SMD footprint. This package provides low thermal resistance and short lead inductance, which are important when switching at high voltages. The 8-pin SON fits within a small PCB area, leaving room for the high-voltage inductor and output capacitors in a compact industrial power module.
